  • Opus and diesel engine crank?

    I am thinking about getting an opus power supply for a via board setup, but am worried about the diesel engine crank being too much for the opus. Has anyone used the opus with diesel engines especially trucks.

    i'm sure it still runs on 12 volt circuit, so what would it matter?

      Diesels rely on the starter motor to pressurize the cylinder more then in a gasoline engine, perhaps the question is "Does the starting sequence of a diesel pull the voltage below the point where an Opus can maintain power during start"?

        Well a diesel engine draws alot more juice(huge starter), thus the dual batteries. When it is cold and you have not plugged in the engine block heater it can take alot of cranking and cycling glow plugs to get it started

          Well, your Powerstroke relies on computers and electronically controlled fuel injection. These engine electronics also need a minimum voltage to operate.

          The only way to be sure is to check it with a digital voltmeter or call Opus.

          Best regards

            That minimum is 5 volts though, a reference voltage, and although I doubt cranking with 2 750cca bateries would drop that low, it just may when it is cold out. Actually, the worst would be during a cold start letting the glow plugs heat up, they draw literally almost as much as the starter, but for much longer. I agree, try a voltmeter.
